ROCK-CRUSHER.

To all whom it may concern.-

Be it known that we, AARON G. DYER and JAMES M. DYER, of the city and county of San Francisco, and State of California, have invented Improvements in Rock-Crushers; and we hereby declare the following to be a full, clear, and exact description thereof.

Our invention relates to certain improvements in apparatus for crushing and pulverizing rock; and it consists in certain combinations and devices, hereinafter described and claimed, and which will be more fully explained by reference to the accompanying drawings, in which Figure l is a vertical section of our apparatus taken through the axis. Fig. 2 is atop section on line a: m, Fig. 1, showing the upper part of the inclosing-cylinder. Fig. 3 is a horizontal section on line y y, Fig. 1, showing the balls and the die J.

A is a base supporting a journalbox, B, through which the lower end of the vertical shaft G extends, and by which it is guided. D is a bevel gear-wheel fitting the shaft, and driven by a pinion, E, upon the horizontal shaft F, to which power may be applied in any suitable manner. A feather, a, is fixed on the shaft 0 and fitted to a keyway in the wheel D,- so that the shaft may have a vertical movement to correspond with that of the cone above without interfering with the action of the gearing. The shaft 0 extends up through a stationary conical base, G, suitably supported upon a fixed frame-work, and upon the outer periphery of which a grooved annular die, H, rests. The balls I run in the groove or channel in thetop of the die H, and a second grooved annular die or shoe, J, of similar shape to the die H, rests upon the tops of the balls and supports the base of the main cone, whichrests upon a suitable bearing or hollow section, W, which is supported bylugs or projections 12, formed on the lower inner side of the inclined hoppershaped rim V, the under surface of which bears upon the upper die, J, as shown in Fig. 1. The conical base G serves to throw the material which falls upon it from above outward, so that itpasses between the balls and the dies. Around the outside flange of this base, and exterior to the dies, is a screen, L, within which the material is retained as long as may be necessary to pulverize it. Outside of this is a rim, M, and upon one side is an opening, m, through which the pulverized material is discharged. The flange forming the bottom of the conical base G, and of the pan surrounding it, is inclined so that the discharge side is the lowest, as shown. Upon this flange is an amalgamated copper plate to retain any free gold. The main cone K has a heavy removable shoe, N, upon the top, upon which the crushing takes place, and the shaft 0 passes up through and is firmly secured to the cone, so that when it is rotated it turns the cone.

lVhen the cone K, carrying the shoe N and supported in the manner above referred to, is rotated by the shaft 0, it causes the vballs to roll around in and between the grooved dies H and J, thereby thoroughly pulverizing the material which passes between them. Above the cone K is a hollow cylinder formed of sec tions 0, set one upon another until sufficient depth is formed, when they are secured together by bolts P, which pass through lugs or flanges Q upon the outside of the sections, and by nuts R, which screw down upon said bolts. The lower section or sections forming this cylinder have the interior made diverging,or curved outward, so as to approximate in shape the upper part of the cone, or its shoe, the edges approaching those of the cone, so that a gradually-narrowing space is formed from the top to the bottom of the cone. The upper section, 0, of the cylinder has arms S, from which a fixed central shaft, T, extends upward, and hasaball or other universal joint, U, at the upper end, which allows the lower end of shaft T to move to one side and out of line with the shaft C as the latter rotates with cone K. WVhen this is done,it will be manifest that one side of the interior of the cylinder will be nearer to. the cone K than the other, and ore or rock which is fed in at thetop of the cylinder will be wedged between it and the cone at the wider portions. This causes the cylinder to travel around with the cone when the latter is driven, and as the space between the two becomes contracted the rock will be crushed, and will settle down, the operation being repeated untilit flows out through the narrow space between the edges of the cone and cylinder. An in clined hopper-shaped rim, V, receives the crushed material at this point and directs it through an annular space inside the upper annular die, J, so that it falls upon the conical base G, and is directed outward into the channels where the balls travel, as before described.

It will be seen that any section of the cylinder can be replaced when worn or broken. The shoe or top of the cone may also be renewed, and the annular dies between which the balls travel, the whole forming a co mplete form of the exterior of the cone, and an inde,

pendent guide-shafthaving its upper end journaled out of line with the cone-driving shaft, substantially asherein described.

2. In acrushing apparatus, a cone having a diverging base, acentral vertical drivingshaft,

a hollow cylinder having a diverging conical base, and an independent shaft standing out of line with the cone-driving shaft, in combination with annular grooved dies and the balls upon which the apparatus rests and is rotated, substantially as herein described.

3. In a crushing apparatus, a vertical rotat ing cone, the supporting-balls, the grooved annular dies, a cylinder surrounding and resting upon the cone, and having its lower section diverging and corresponding with the exterior surface of the cone, and an independentguideshaft for said cylinder, arranged out of line with the cone-shaft, in combination with a guiding chute or hopper, V, by which the ma terial escaping between the cone and the cyl- 4o inder is delivered between the balls and dies, substantially as herein described.

at. In a crushing apparatus, the cone K, the vertical rotating shaft, the cylinder 0, having its lower part shaped similarly to the cone upon 5 which it rests, and ashaft independent of the cone-shaft, extending upward at an angle thereto, in combination with grooved annular dies, intermediate balls, and a conical base, G, substantially as herein described.

5. In a crushing apparatus, the vertical rotating cone K, shaft 0, and the superposed cylindrical casing O, in combination with the shaft T, the ball U on said shaft, and the box in which the ball fits,whercby the angle of the shaft may be changed relative to the axis of the cone, substantially as described.

In witness whereof we have hereunto set our hands.
